Targeted electrical distribution reliability improvements are a major component of this phase of the program. Many lines are being converted from overhead lines to underground, where they will be less susceptible to outages caused by trees contacting lines or vehicular collisions. Automated line devices are being installed to quickly isolate outages and minimize the number of customers affected when issues arise. We are adding connections to enable greater flexibility to reroute power in the event of an outage. Some lines are being relocated to improve their accessibility for repair crews, and other aging lines are being strengthened with material and technology upgrades.
At higher voltage levels, we are coordinating transmission improvements statewide, including proactive replacement of aging assets to reduce the risk of failures. Transmission line conductor is being replaced with modern materials to better withstand weather and aging. Additionally, at some electrical substations, we are managing targeted replacement of older major equipment, including circuit breakers and transformers. At others containing significant quantities of aged equipment, the substations are being rebuilt.
The projects under the umbrella of the Grid Investment Plan are being tailored to each community based on current infrastructure and needs for investment. Project teams are coordinating with local stakeholders to maintain open communications, minimize disruptions, and provide safe implementations of upgrades and replacements.
